MFactory Final Drive Gears. Final drive gears are cut from high quality fully-carburized forged nickel-chromoly steel while also benefitting from a proprietary heat treatment process. As a result we are proud to offer enthusiasts the best final drive gears on the market today. By changing you final drive gear ratios, you can experience a dramatic increase in acceleration, giving you on average a 10-15% increase in torque throughout the entire rev-range over the OEM final drive. 

Made from imported Japanese steel these final drives are 'forged' and 'cryo-tempered' for unsurpassed toughness. As used on several Championship winning race cars.
